HAND STAMP.

Application filed December 22, 1925. Serial No. 77 065.

This invention relates to hand stamps, and particularly to the typeknown as rubber stamps and has reference more specifically to the handleand itsconnection with the base or lower portion of the stamp.

An object of this invention is to provide an improved connection betweenthebase of the stamp and its handle for permitting a yielding orcompression of the handle in the application of the stamp to a surfacefor insuring a uniform and even pressure of the stamp at all ends andsides thereof so that even though the hand is not held in true alignmentwith the surface, the stamp will effect an even impression. Another.object of the invention is to provide a handle with a neck portion ofrubber or yieldable substance for connecting the base of the stampwiththe handle, and to provide a Stlfifil'llllg element mounted tomaintain the neck in proper alignment with the handle and so mounted asto adjust the tension and to permit of the pro-per equalizing of thebase of the stamp to the surface when subjected to pressure.

The invention still further aims. to provide an elastic neck portionwhich is detachably connected at one end to the handle of the stamp andat its other end is compressed to the desired degree against the base ofthe stamp to support the base on the handle in such position that whenpressure is exerted on the handle the neck portion maybe compressedaxially and at the same time permits the base portion to rock or moveupon the lower end of the neck portion to assume its proper positionagainst thesurface when the handle is forced toward the same. -c

l A still further object of the invention is to provide a readilydetachable neck of flexible material and to provide a couplingcarried bythe neck to stiffen it against undue lateral bending and to placetheneck under desired tension, the connection being independent of thehandle to provide the re quired resilient connection between the parts.

The, above and various other objects and advantages of this inventionwill in part be described in; and in part be understood from thefollowing detailed description of the present preferred embodiment, thesame being illustrated in the accompanying drawing. wherein:

' Fig. 1 is a vertical central section taken through a hand stampconstructed according to the present invention. L

Fig. 2 is a transverse section taken on the line 22 of Fig. 1, andlooking downwardly toward the base of the stamppand Fig.3 is a viewsimilar to Fig. 1, show drawing 10 designates a threaded forthemajorportion of its length but which is unthreaded atits' inn-er or upend toprovide chamber orspace 11.

A neck 12- of rubber or other elastic material has an elongatedexternally threaded shank at its upper end adapted to be screwed intothe opening in the handle and provided with a stop shoulder 13 at thelower end of the shank which abuts the lower end of the handle andlimits the insertion of the shank into the handle to leave the chamberor space llfree. Below the shoulder 13, the flexible neck is providedwith a downwardly flaring ring portion 14 which merges into a foot piece15 flaring annularly from the ring portion 1 1 and which is providedwith a con v cavity 16 in its under side permitting the spreading andflattening of the foot port1on 15 against the upper suriaceof the base17 of the stamp.

The concavity 16 is relatively broad and the base portion 17 has arelatively large central opening 18 therethrough which registers withthe. cavity 16, and with an axial opening which is vtermed through theresilient neck 12.1 Secured by an adhesive, or the like, is the body 19of the stamp which may be of rubber or the like carrying suitablecharacters or forms by means of which the 'impression is to be. made.The opening 18 throughtthe base 17 is flared or counterbored at its.lower end to accommodate an anchoring plug 20 which is of conical formhaving its apex portion extending upwardly in the opening 18 and withits enlarged portion in the counterbore or countersink of the opening18. The plug 20 carries an upwardly eXtending eye 21 at its apex andinto which is connected a hook 22 or the like carried on the lower endof a rod 23 which serves as a connecting member between the neck 12 andthebase 17, and which also provides a stifiening element for the neck12. The upper end of the rod 23 extends beyond the neck 12 and isscrewthreaded and receives thereover a washer 2 L knurled or roughenedat opposite sides to frictionally seat upon the upper end of the neck 12and to receive thereon a binding nut 25 adjustably threaded on the rod12 to draw the same upwardly through the neck 12 to the desired extent.T he rod and nut provide a tension means for compressing the neck 12 tothe desired degree against the base 17 of the stamp.

The chamber 11 permits the nut 25 and its rod 23 to move upwardly whenthe handle 10 is forced downwardly with sufiicient pressure to furthercompress the lower end of the neck;

In Fig. 3 a slight modification is shown wherein the foot piece 26 ofthe neck is provided with a relatively large concavity 27 *for receivingthe hook 22 or" the rod 23 therein when the base 28 of the stamp is ofmetal or other relatively thin material. In this instance a relativelyshallow tapering plug 29 is secured through a correspondingly formedopening in the base 28 with the 'eye 30 of the plug engaging the hook 22and lying within the cavity or recess 27. The stamp'or block 31 issecured to the lower side of the base 28 in any suitable manner.

In use, the binding nut 25 is tightened to compress the foot piece 15 ofthe neck against the base 17 of the stamp so as to compress the neck tothe desired extent and establish a firm connection between the neck andthe base. The neck 12 is now screwed into the handle 10. When it isdesired to make an impression on a surface, the handle 10 is grasped inthe usual manner so as to force the stamp 19 against the surface. Duringthis action the foot piece 15 is further compressed against the base 17and is supported against undue spreading by the ring portion 14, whichlatter however is also capable of compression and of being spread to aslight extent. During this compression of the lower end of the neck 12,the rod 23 with its nut 25 is permitted to move upwardly into thechamber 11 of the handle so that there will be no rigid connectionbetween the base and the handle.

Should the pressure of the handle be un evenly applied to the base 17,the rod 23 may swing at its lower end upon the eye 21 so that the base17 may seat in a position substantially parallel with the surface uponwhich the impression is made. This swinging or universal action ispermissible in the form shown in Fig.1 by reason of the opening 18through the base 17, and in the modi fied form shown in Fig. 3 by reasonof the enlarged recess or cavity 27 and the arrangement of the hook 22and eye 30 therein.

The handle is thus connected to the base of the stamp by an axiallycompressible connection, and a connection which has universal movementas well as a connection which is reinforced above the joint and which isadjustable as to its rigidity.

It is of course understood that various changes and modifications may bemade in the details of construction and design of the above specificallydescribed forms of the invention without departing from the spiritthereof, and being restricted only by the scope of the following claims.

What is claimed is:

1. A hand stamp comprising a handle, a resilient neck carried by thehandle, a base provided with a stamp, and a pivoted connectionadjustably secured between thebase and the neck for initiallycompressing the latter and holding the base thereto.

3. A hand' stamp comprising a handle having a threaded opening in itslower end, a resilient neck screwed at one end to said opening, a basefitting against the lower end of the neck, a rod pivotally'connected tothe base and extending upwardly through the neck, and an adjusting nutcarried on the upper end of the rod for drawing the base against thelower end of the neck and compressing the latter to the desiredrigidity.
